In the event of damage to an offshore power transmission line, these cables have to be delivered quickly to the accident site. Krebs Korrosionsschutz GmbH executes such jobs with its octuple-tyre electronically steered ModulMAX SP-E in self-propelled mode.
One of these cable drums, in which the high-tension cable is coiled in a horizontal position, recently had to be transported from the warehouse to the pier for transfer to the ship by a mobile crane. In addition to the 36 axle lines of their Cometto SPMT fleet, Krebs now has a new ace up its sleeve for these tasks with its 3,000 mm wide and Faymonville ModulMAX SP-E with 8 tires per axle line.
In the 6-axle version, the self-propelled heavy load module with electronic steering is the ideal choice for this mission due to the minimised passage height of the hall door. Stefan Krüger confidently steers the ModulMAX SP-E with its 372 kW power pack in the lowest gear through the hall door. "Six inches of space between the load and the bottom edge of the door are sufficient," he says with a wink, explaining the precision work.
Unique twin-engine solution
The power pack is actually designed to power up to 48 axle lines of the ModulMAX SP-E self-propelled vehicle. It is therefore hardly burdened by the 6-axle bogie for this transport task. However, the unique twin-engine solution makes it possible at any time to adapt the power pack to the respective transport task and vehicle combination. Proven technology from Cometto, which is responsible for the manufacture and servicing of the self-propelled modular transport vehicles within the Faymonville Group.
The driver decides whether he wants to operate the power pack with one or both diesel engines. "For the cable drum transport we use engine B with 186 kW," explains operation manager Jörg Neuhäusel. "With this unique technology we can always ensure that we consume little fuel and that the engine is operated within its correct temperature range."
Self-propelled technology for offshore projects
Thanks to the electronic multi-directional steering and an axle compensation of 650 mm, it is easy to transport the 60-tonne cable drums with a diameter of 6 metres and a height of 6.25 m to the loading point, where Krebs’ own mobile crane is waiting. Once again, transport equipment from the Faymonville Group makes a successful contribution to German offshore wind farms.
